seconds. good evening. thank you for joining us. it's friday night and all across america, all too many parents are holding their breaths on the football sidelines. as concern rapidly intensifies over the long-term effects of taking hits to the head on the field. can new helmet technology and new coaching tips lessen the impact of those violent hits? here's abc's ryan smith. >> reporter: when jordan dalton's school day ends he has one thing on his mind. football. dalton, number 71 for the north wood high school chargers, is a
senior on the varsity team. identified as a high-risk player. high risk for concussions because of those hard hits on the field. but it's those hits on the field that worry his mom cara. >> when i see jordan get hit, i'm usually thinking about how hard was that hit? is that hit going to turn into a concussion? was it hard enough for a concussion? that's the part that i don't really know. >> reporter: across the country parents like cara are questioning just how safe the game is. preoccupied a big hit could land their son in an emergency room or worse. since july there have been 11 high school fatalities, seven directly related to a traumatic injury. the most recent? >> slipped past a tackle -- >> reporter: luke shem, number 4, scoring in a playoff game two weeks ago after taking a hit in the third quarter and running
was flown to a hospital where he died the next day after his family removed him from life support. >> our beautiful gift from god months longer with us. >> reporter: tonight another high schooler in southern california still recovering at a medical center four weeks after what appeared to be a routine tackle. dramatic video showing josh nava stumble off the field. needing emergency surgery to stop the bleeding, swelling, and pressure on his brain. >> he looks like he's in pain. >> reporter: little is known about how hard nava was hit but the helmet he wore contains sensors able to catch that data. but a school official said the device malfunctioned that night. concussions. the long-term effects of multiple concussions or even just one concussion. >> reporter: so is a team of researchers from university of north carolina who determined jordan to be an at-risk player for head injury. hard hits to his head from early in the season flagging him, turning him into a subject in their three-year study aimed at
knew. >> i didn't realize in the beginning that he was the one getting more impacts than anybody else. impacts mean. >> we're trying to better understand if we can change the behavior on the field. >> reporter: dr. kevin goskowicz leads the study known as bemo, short for behavior modification. >> this is footage of teams in our study. they have this system in their helmets. >> reporter: researchers track, in realtime, the number and strength of hits to players' heads. that data, some of which is shown in this video from the study, reveals who they say may be at risk for concussions. >> what's 95-g like in the context of a car? >> 25 miles an hour. >> reporter: coaches staged an intervention with jordan, focusing on drills to help him understand what's seen as a safer way to play. how-to videos.
it's based on a method of tackling and blocking known as heads-up football, an nfl-funded and promoted program emphasizing shoulders when tackling, not with their heads. a recent analysis found players between the age of 5 and 15 playing on teams adopting the program had a 76% reduction in injuries and a 29% reduction of concussions during games. jordan works on his form during specific drills at practice. and then reviews video of it from previous games. >> the impact that you took on 95-g hit. >> my stance is terrible and i'm way too far down. >> these guys are used to tackling with all their might, all their force. they don't want to think. the right way? >> t message we're sending is you've got to play smart today, to be able to play later. >> reporter: he showed me video of jordan from early in the season which he says shows poor form. >> what's he doing wrong? >> well, you can see he's head
to head right there. that's a high impact. >> reporter: he compared to it a video under the friday night lights. >> same exact play but you're going to see he's going to get out? front, going to get those arms up a little earlier. at impact that's better clearly technique. >> reporter: he's part of the nfl's head, neck and spine committee. and dismisses scrutiny arising from his nfl connection. >> you're on an nfl committee. are you concerned that some people will see your results and be do you remember yus of those results? >> i'm an unpaid consultant or advising them about what we see as ways to ilprove safety in their sport. i'm much more interested in trying to make a difference at this youth level. >> reporter: and he's not the only one investigating a way to make the game safer. eric schwartz, former rugby player, knows tackles in that game almost never involved the head. >> your thought is if they learn it without the pads, rugby style, they won't do it as much
during the game. >> we hope it will carry over. it eliminates one player from basically turning their body into a projectile to blow somebody up. >> reporter: known as helmetless tackle training, he used university of new hampshire wildcats as test recruits. and he says there's some early evidence it's working. >> we've been able to identify that some of them actually decrease in the number of impacts per exposure. >> reporter: eager to help younger players, swartz approached a nearby high school and enrolled them in a study. wired with monitors they practiced tackling without helmets and pads. unh researchers counted more than 50,000 head impacted this season. >> how many times cab a high school player face contact in a game? >> they can receive 30, 40 impacts to the head in a single game. >> reporter: swarts' catching
the eye of ge, under armour, and study. >> i understand there is a level of scrutiny and skepticism. i get that. that was just one of the opportunities that was available that we pursued. >> reporter: these studies coming at a time when numbers of high school football players are decreasing. last season there was nearly 10,000 fewer high schoolers playing the game than the previous soap. season. still, football is by far the most popular team sport in high school. >> you've turned on the lights and gave their biggest positiony man a name. >> reporter: dr. julian bales, played by alec baldwin in "concussion," a neurosurgeon and one of the leading surgeons on traumatic brain injuries. >> sensors, smart helmets, having weekly hits is all important. hopefully technology is going to be a big part of solving this concussion issue in sports. >> reporter: many agree nothing can eliminate the risk of taking a big hit on the field.
>> do you worry about facing one of these life-threatening injuries on the field? >> it's in the back of your head. if you get hit you might think, that could be something. but you have to keep playing. >> reporter: for "nightline," i'm ryan smith in pitsville, north carolina. next, an abc news exclusive. barbara walters with donald trump and his family. the children telling us what

might not work out? concerns. we have a great chemistry. and to be with the man as my husband, you need to know who you are, you need to be very smart and quick and be there for him when he needs you. equals? >> i would say, yes. >> i would say no, no, i think she's far greater than the 50%. no, we have a very -- a pretty much equal relationship, wouldn't you say? >> reporter: i wondered if melania has ever taken his husband to task on his tone toward women on the campaign trail. >> did he make a derogatory comment attacking carly fiorina? >> i think women all over this country heard very clearly what mr. trump said. >> you know your husband has come under fire here and there for making disparaging remarks about women. does this bother you? >> it doesn't bother me. he treats everybody the same.
